WHEEL FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 695,805, dated March 18, 1902, Application filed llugnst 21, 1901- Serial No. 72,765. (No model.)

To aZZ whom, it may concern.-

Be it known that I, HAROLD EDENBOROUGH, engineer, a subject of the King of Great Britain, residing at Martham House, Snaresbrook,

in the county of Essex, England, have invented new and useful Improvements in \Vheels for Vehicles, of which the following is a specification.

My invention relates to the wooden wheels of field-guns, wagons, carts, and other vehicles, and has for its object to enable the wheel to be readily tightened up when the fellies and spokes become loose in consequence of shrinkage of the wood.

Reference is to be had to the accompanying drawings, forming part of this specification, wherein I have illustrated the preferred construction of rim and tire.

Figure 1 is a face View of a segment of the wheel-rim, tire, and tightening device. Fig. 2 is a cross-section, and Fig. 3 is a part edge View of the same.

The same letters of reference indicate the same parts in all the figures.

a is the wooden rim of the wheel, built up offellies, as usual, and made of double conical form on the exterior circumference, the two coned surfaces I) I) being preferably symmetrical. Viithout in any way confining myself to a particular angle, it may be mentioned that the preferred angle of conicity is substantially as shownnamely, about forty degrees to the axis of the wheel-but it may be greater or less.

Between the outer tire-band h, forming the head of the wheel, and the wooden rim to are interposed two similar opposed series of segmental wedges c o, oppositely coned on their internal circumferences to correspond to the 0 cones b b of the wheel-rim, the two series of wedges c 0 being applied upon the wheel-rim from opposite sides and tightly connected by transverse bolts (Z, a sufficient interval separating the two series a c to allow of their being drawn closer together in order to tighten up the wheel when required in consequence of the shrinking of the wood. The screwbolts d are preferably shouldered, as at e, and have squared ends f for the application of a spanner, the shouldered ends being received in countersunk holes 9 in the one wedge c,

the shanks of the bolts passing through clearance-holes in that wedge and their threaded ends screwing into corresponding holes tapped in the opposite wedge c, notches z'being made in the wheel-rim a to give passage to the bolts. The outer band 71, besides covering the gap between the series of wedges c c at opposite sides, affords the necessary abutment to enable said wedges to exert the required wedging action between the band h and the rim a when the screw-bolts (Z are tightened up, the pressure due to the wedging action serving both to tighten up the wheel and to keep the outer tire-band h in place. Thejoints between the adjacent ends of the segments b should preferably be alter= nated with the joints of the follies compos ing the rim a. Boltslmay be passed radially through the band h and rim a, the segments a being notched at their inner edges to clear the bolts, as shown at m in Fig. 3.

The spokes 7c of the wheel are tenoned into the fellios of the rim in the usual manner and are preferably shouldered to abut against the 7 5 inner circumference of the rim andsimilarly as regards the hub.

Having now particularly described and ascertained the nature of the said invention and in what manner the same is to be performed, I declare that what I claim is- 1. A wooden wheel having its rim coned in opposite directions on the external circumference, in combination with an outer encircling tire-band forming the tread of the wheel, 8 5 two opposed series of segmental wedges located between the rim and tire-band, said series of wedges being oppositely coned on their internal circumference to correspond to the double-coned circumference of the wheelrim, and transverse bolts adapted to draw the oppositely-coned segments toward each other with a wedge-like action so as to take up slackness of the joints of the woodenpart of the wheel and tighten the tire-band on the 5 wheel, as described.

2. In a wheel, the combination of a rim having its external surface inclined from the center downwardly and outwardly and provided with transverse grooves or notches, a flat the band, segmental wedges arranged between the band and rim and having flat outer faces and inclined inner faces, and transverse'bolts engaging the wedges to draw them toward faces and inclined inner faces and provided with notches at their inner edges opposite the bolts securing the band to the rim, and transverse bolts engaging the wedges to draw them together, said bolts being in the grooves or notches of the rim, as set forth.

HAROLD EDENBOROUGI-I.
